LG G3 D855 SD Card Slot Error: Unexpected Removal & Formatting Issues with Multiple Cards

Hello.
I have a problem with my Lg G3. Yesterday I received a message that the SD card was unexpectedly removed. Since then, a message appears from time to time to format the card. It formats up to 20% and throws me to the menu or undergoes formatting, but in a few minutes there is a message about an error in the card or the card file system. Later the phone stopped responding to the card insertion. What could be the reason?

I tried with various cards of different capacities and manufacturers (they work perfectly in Windows). I did a software update. From android 6.0 I went back to 5.0. It does nothing. I formatted cards in Windows with file format changes. No effect.

Since reinstalling the software did not do anything, the only thing left for you is to replace the card slot. And did you hard reset too?

I have done several times. Unfortunately it didn't work. Does anyone know what price the service can call? The cost of a slot in China is about $ 4.

Unfortunately, you have to ask for it yourself on the website, everyone has a different price list.
